HARRY R. BARTELL, OF ST. LOUIS, MISSOURI, ASSIGNOR '10 CAST STEEL TENDER FRAME COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF DELAWARE.

TENDER FRAME.

Application filed April 3,

To all whom it may concern:

Be it known that I, HARRY R. BARTELL, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Tender Frames, of which the following is a full,clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this application.

My invention relates to railroad rolling stock and consists in .an improved underframe especially adapted for locomotive tenders.

The main object of my invention is to produce an economical underframefor tenders of relatively small capacity, such as are used in industrial or short-haul service. I secure this object by providing a tender frame adapted to be mounted upon a single truck and otherwise supported from the locomotive frame and by forming the underframe of a one-piece casting whereby the metal may be distributed most efficiently by providing sectional areas at different points suflicient to take care of the stresses there encountered without the introduction of surplus metal such as is usually found in built-up structures.

In the accompanying drawings which illustrate a selected embodiment of my invention and the modification thereof.

Figure 1 is a top view of one-half of my improved underframe, it being understood that the other half is a duplicate of that shown.

Figure 2 is a longitudinal vertical section through the center of the underframe.

Figures 3 and 4: are transverse vertical se tions taken on lines 3-3 and 44, respectively, of Figure 1. I

Figure 5 is similar to Figure 1 but illustrates a modified construction.

Figure 6 is a side elevation of the structure shown in Figure 5.

Figures 7 and 8 are transverse vertical sections taken on lines 77 and 8-8 of Figure 5.

The underframe casting, includes longitudinal draft or center sills 1 and 2 and side sills 3. The longitudinal sills 1 at the lefthand end of the frame merge with the end.

sill 4 and'form therewith a drawbar pocket 5 and are provided also with projections .6

for supporting a removable carry iron 7.

The longitudinal sills 2 at the 'righthand end of the car project beyond the end sill 8 to form members 9 of extended area adapted to be secured to the rear of the locomotive frame 10. Members 9 13.18 provided with projections or flanges .11 whereby they are adapted to cooperate with corresponding surfaces on the locomotive frame and to vertically engage the latter.

Intermediate the end sills is a single transverse member 12 which forms a body bolster adapted by means of its removable center plate 13 to rest upon the center plate of a truck bolster. The longitudinal sills 1 and 2 ofthe frame increase in depth from bolster 12 to the end of the frame and have their maximum depth at the ends.

. By means of this construction the tender frame may be mounted upon a single truck located near its longitudinal center and any further necessary support of the truck frame is provided by its connection to'the locomotive frame. The increases in depth of the inain longitudinal sills of the frame from the bolster toward the ends-take care of the loads near the ends of the frame, and the frame as a whole, in combination with a locomotive frame, may be likened to a cantilever construction.

The underframe described is economically produced, eliminates one truck from the usual construction, and when combined with .a member 14 extending between the center or draft sills 15 and 16 only and formed integrally therewith. This arrangement enables the transverse members 17 and 18 to be located wherever desired and independently of the center of the tender truck.

In Figure 5, for example, the two cross beams are provided intermediate the frame ends 19 and 20 Without moving the truck supported member from its preferred location and without the provision ,of a third unnecessary cross member.-

' 'I'n this'embodiment of my invention the longitudinal sills 15 and 16 diverge at their forward portions instead of being ofi'set as are the corresponding sills of the preferred form but in both forms the truck supported member is positioned at the inner portions of these draft sills.

In Figures to,8 I indicate equalizer ful' orums 21 and springv shackle brackets 22. Similar elements may be provided on, the frame shown in Figure 1 and other additional element attaching means'may be provided on either frame.

Various other modifications in the proportions and dispositions of the parts shown may be made without departing-from the spirit of my invention as expressed in the accompanying claims.

I claim: 1. In a tender oneiece cast underframe,

a truck supported boster positioned intermedlate the ends of the underframe,

body carrying center, side and endsills and a member projecting at one end of the under frame and adapted to be supportedly attached to a locomotive frame below the plane of said sills. r

2. In a tender oneiece cast underframe, a single bolster positioned intermediate the ends of the underframe, and a sill member atone end of the underframe projectin and provlded with horizontal surfaces for vertical engagement with cooperating surfaces on a locomotive frame.

3. A tender underframe casting including integrally formed longitudlnal SlllS, end

- mediate said sills and sills,-a single intermediate cross member forming a bolster, a drawbar pocket with carry iron supports at one end of the. longitudinal sills and below the plane of sad bolster, and an extension at the otherend of'the longitudinal sills below said plane for attachment to a locomotive frame.

4. A tender underframe comprising a one piece casting having a transverse member intermediate itsends formin a body bolster, sills merging with said inem r and extend- .ing therefrom downwardly and longitudinally of the underframe to points of maximum depth adjacent to the ends of the ing-outwardly and downwardly from each side'of said body bolster to points of maximum depth adjacent to the ends of the underframe.

In testimony whereof I hereunto aflix my signature this 13th day of March, 1923.

H. R. BARTELL.
